"I came up the with idea of the cake as a vehicle to celebrate her name change while having an informal family dinner with those that support, love and care for her," Gabrielle's mom said of the surprise. "It was a spontaneous event because we had been waiting over 2 months to receive her legal name change, and felt it was an opportunity when those that cared were there to celebrate this new beginning."

"I was not expecting her to get so emotional that she became speechless," Rose said. "My daughter is never speechless. I knew at that moment my child came back to me. She was on her way to who she had been from birth."

Gabrielle has a YouTube channel where she documents her transition and provides advice to other transgender teens, and, of course, her mom has made an appearance.

"I hope when people see this video, they see the importance of names and pronouns, because they are so important to someone's transition," Gabrielle said. "It makes them feel valued and important, and that makes transitioning a lot easier."
